Be it lm'own that I, WILLIAMA.'LEE, Jig, a

, citizen of the United States, and'a resident 'of the borousgh of Brooklyn, county of Kings,

ing wool either efore or after it is combed. Such machines commonly comprise two or more sets of rolls, between which the wool asses successively and is drawn and reuced inthickness y one set of rollers at agreater surface speed than the other,

while the leveling of the woo1-is obtained by means of bars (termed fallers) provided f with pins engaging the, wool while it isbeing drawn and traveling in the same direction as the wool. According to the manner of disposing of the product three t esof gilloxes are distinguished: can-gi ls, having cans to receive the web or sliver, as" it is called, (sometimes the sliver is allowed to drop on an apron, dispensing with the can;)

- spindle-gills,- in which the web after being twisted (in which case it is called a slubbing is wound on a bobbin, and balling gills, in which the materialafter (passing between the rolls is wound or balle by means of balling-rolls.

My invention is applicable to each of the three types abovementioned, and has for its obiect to insure an im roved operation in the fol owing respects: lrst, to obtain a constant draft, b which term I mean the ratio r of the speed wit which the sliver is drawn or delivered to the speed with which the sliver enters the machine. The detailed descri tionfollowin hereinafter will explain t e difliculties w 'ch the customary: gill-boxes present inthis particular. Second, I improve the action of the stop-motion or knockoff motion, which is intendedto stop the machine after a certain len th of material has been delivered, but whic does not fulfil this purpipse satisfactoril in ordinary gillboxes. bird, in all gil -boxes aprons are employed for drawing the sliver, which aprons draw more or less, according as the are new or Worked into sha e, even thoug their s eed be the same. have provided means or adjusting the draft of these-aprons without. altering the ratio of delivery s eed to entrance speed. Fourth, with specia ref- .Fig. 2, illustrating the a cipal rol near the bac rolls.

boxes, I have added to theme set of pressrolls or take-u rolls, with advantages fully stated hereina er.

Reference is-to be had to the accompanym 7 rencete spindle gill-boxes and balling igure 1 is a lanview of so much of a can gill-box as is s'u cient to illustrate my invention, with parts omitted for the sake of greater clearness, Fig. 2 is a vertical section taken substantially on line 2 20f Fig; 1 Fig.

3'is a cross-section on line v3 3 of Fi 2; and

Figs. 4 and 5 are vertical sections similar to lication of m invention to a spindle gil ox and a ba ling gill box, respectively. j r i A cangill-box comprises three sets of priners-th e back rolls'A, which feed the'material into the machine; the front rolls B, which, together with the apron C, passing between them, draw out the sliver as the front rolls rotate at a higher rate of surface speed than the back rolls, and the press-rolls ortake-up rolls D, which control the deliver of the sliver.

ary construction; but it will be understood that they extend arallel with the roll-axes andtravel forwar from the back'rolls to the front rolls, their upwardly-projectin pins E engagin the-forwardly-travelings 1ver and their en s E' meshin into the threads of the screws F F; commonly called the back shaft, which b means of bevel-gears G and spur-gears 2 drives the screws F F, controlling the movement of the fallers, in the usual way, the fallers droppin when they reach a point near the front ro ls, thentraveling backward in their lowerosition and rising again when All these parts may be of the customar therefore deeme it unnecessary to illustrate them fully.

' My inventlon consists particularly in the gearing H, which generally includes changegears, so that the relation of the back-roll s eed to that of the fallers may be varied.-

p p I have not illustrated the fal 7 ers'E in detail, as they may be of the custom G in 'cates the drive-shaft,

construction, and I have he front rolls B' are driven by caring J,

which includes chan eears or ot er means for varying the spec o the front rolls without alterin the speed of other parts of the machine. he press-rolls D are driven by roll gearin H.

v changed the rate of-draft will remain con-' stant and will not be affected b an'yadjustment of the. front-roll s eed. he knock-off motion is driven directl y from the press-rolls D, as by gearin L, which may include change-gears. With this arrangement (as long as the gearing L is unchanged) the machine will stop automaticall after a constant number of revolutions of t e'press rolls, or, in other words, after delivering a predetermined length of the product.

of the front rolls be increased too much, the.

adjustment of the front-roll speed.

The apron G, being made of leather or othermaterial and wor in conjunction with the fluted front rolls B, is at first ractically smooth when new, but gradua ly becomes corrugated transversely owin to the pressure of the intermeshing rollutings. An apron when new will therefore draw less material per revolution of the front rolls than after the apron has become shaped to the flutes of the rolls.

Since, however, the massrolls take up and deliver the materia at a constant rate of speed, it follows that with a new apron there is danger of the 'material being drawn too hard between the front rolls and press-rolls and not enough between the front rolls and fallers. To overcome thisdifficulty, the gearing J is adjusted to properly increase the speed of the front rolls B when a new apron isinserted. It will be observed that such adiustment has not the least effect onof speed of Should the speed:

the draft-that is, on the rate portion ofthe material between the front rolls and press-rolls will become slack, thus showing the operator that the s eed of the front ro s should be reduced. his slackness also appear as soon as the apron 0 becomes corrugated in use,.and consequently draws more material er. revolution of 'thefront rolls than it did when new- The operator will then substitute the necessary changegear to reduce the number of revolutions of the front rolls. I It will therefofe be understood that my invention provides means for adjusting the speed of the front rolls as may be required by the varyin condition of the a mu 0 without affecting tie rate of draft- 1: at is, if the press-rolls D take up and deliver the material six times as fast as it is fed by the back rolls A this relative rate of s eed or draft will be preserved irrespectiveany of machines when equi emcee not the case, however, when the press-rolls are driven from the front rolls, as has been the practice hitherto.

As re ards the advantage of driving the knock-o motion direct from the press-rolls,

it will be obvious that this insures the delivery of a predetermined length of sliver, since the press-rolls (being generally smooth) always feed -.ie same length of material per revolution. Heretofore it has been the custom to drive the knock-ofl" motion from the front rolls, which, as above stated, less or revolution, according to the varying condition of the apron. tion, which is operated after a predetermined number of revolutions, will therefore in this old arrangement be irregular in its action as re ards the length of material'delivered.

Vhen ap lying my invention to gill-boxes of the spindqe type or balling t in Figs. 4 and 5, respectively, the back rolls, front rolls, and fallers in exactl the same manner as herein'before descri ed. In the spindle gill-box, Fig. 4, even the press-rolls are exactly the same as in Fi 2, and'the onl difference between the two structures is tli at the sliver is twisted into a 'slubbing after assing between the pressrolls and is wound on a bobbin M in the same manner as in ordinary spindle gill-boxes. I may here remark that spindle gill-boxes as e, as shown The knock-off mofeed more or may arrange usually constructed have no press-rolls, but

simply a stationary 'de-rod.

In the balling gifi b ox, Fig. 5, inasmuch as the sliver is wound on the customa bobbin N, resting on the balling-rolls 0 an movable upwar y as the balling operation proresses, the press-rolls D are arranged at diferent levels, and I prefer to employ three rolls--two at the same level and the third at a different level and in an intermediate position-that is, rear of the other. Balling gill-boxes as heretofore constructed have no press-rolls between the front rolls and the balling-rolls.

. The advanta e of adding press-rolls, as described, in -boxes of the spindle type and balling t 0 lies in the feature of making the knock-o motion dependent directly upon the speed of the press-rolls, which therefore become measuring-rolls to sto the machine after the required length 0 material has been delivered. The addition of pressrolls when driven as described also preserves a constant rate of draft, as has been fully exlained in connection with the can gill-box. t will be understood that in all hree types ped according to my motion is driven at to the by any invention the knock-'0 a constant rate of speed"relativel back rolls and is not to beafi'ecte change in the s eed of the front rolls.

Various mo lfications maybe made without departing from the nature of my invention.
